The Scientific Revolution changed the view that people had of the universe, changing it from a medieval view to a more modern one.
Specifically, the Scientific Revolution altered the way people thought of the Earth and the heavens. They had previously thought that the Earth was the center of the universe and that the heavens revolved around it. With Copernicus this changed and people came to know that the Earth orbits the sun.
More generally, people came to see the universe as a place that could be understood through science and reason. They stopped looking for divine or supernatural explanations for things and instead looked for natural laws that could explain the universe.
